uigd-virus-files-remove-restore

The Uigd virus is a computer infection that behaves as data locker ransomware. Unknown hackers have created this infection to obtain access to computer systems without notifying their victims before the attack reaches its end. Without realising you may have activated the malicious payload of this ransomware on your PC and let it encrypt your files. As a result, these files appear with the .uigd extension. They remain inaccessible until you find a decryption solution or a backup option. No matter how important are .uigd files, we advise you to skip solving the problem as hackers say in their ransom note _readme.txt. The main idea of this message is to extort you into paying BitCoin to the criminals who have created this infection known as STOP/DJVU ransomware.

Uigd Virus – How Did I Get Infected?

Uigd virus has one main purpose and it is to attack your files. Other recent variants of the same ransomware campaign include the Eyrv, Vlff and Miia infections. All these strains have the same code as Uigd virus.

Ransomware infections aim to end up on computer systems without even notifying people. The ransomware activation file may have been sent to you in the form of an email attachment, that portrays an important document, for example:

  • Work-related files.
  • Receipts.
  • Invoices.
  • E-Tickets for events or flights.

These documents can be designed to contain malicious macros in them. When this malicious code is downloaded and run on a computer system, it may trigger the following infection process:

Another method of infection used by STOP/DJVU viruses, like the Uigd virus is via uploads on various third-party websites that advertise malware as free downloads. You may be seeking different types of files and end up with ransomware infection on your machine, for example:

  • Self extracting archives or regular archives.
  • Fake installation files.
  • Software patches.
  • Cracked portable versions of apps.
  • Software or game cracks.
  • Key generator (or Keygen).

These files often contain the malicious script that triggers the infection with Uigd ransomware.

Uigd Virus – What Does It Do?

Once the Uigd virus has already caused an infection of your computer, the first thing it does is run a process that connects to a remote server that is hosted by the cybercriminals who have created this malware. From there, the Uigd virus downloads the malicious files and they could reside on your computer under different, often random names and in the following folders:

  • %Windows%
  • %SystemDrive%
  • %LocalLow%
  • %AppData%
  • %Local%
  • %Temp%
  • %System%
  • %system32%

Another file that is also dropped on your computer system is the _readme.txt ransom note, that has the following contents:

STOP ransomware virus ransom message

Be advised, that this virus may also attack your Windows Registry Editor, more specifically add value strings in the following registries:

  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

Doing this will allow the Uigd ransomware to be run each time you turn on your computer.

What Are .uigd Files

The .uigd files are the result of this virus encoding your important data. They are copies of your original files, with a significant difference that they are encrypted, using the AES encryption algorithm. This means that the core structure data of the files is altered and they now can only be recovered, using an online or off-line decryption key.

The main files that are attacked by the virus are encrypted, based on their file extensions:

  • Audio (.mp3, .wav, etc.).
  • Picture file kinds (.jpg, .png, .etc).
  • Videos (.mp4, .avi, etc.).
  • Archive file formats (.zip, .rar, etc).
  • Documents of different types (.docx, .pptx, etc.).
  • Others.

After .uigd virus finishes encrypting your files, it leaves them looking like the example below displays:
